Similar to "Beep Beep," “You’re So Fly” features an upbeat old school vibe with a fun music video. The members of BTOB are seen fawning over a woman who appears to be played by a man, causing some disagreements in a convenience store.

The music video teaser contrasts the chic and stylish poses that the members showed in their image teasers but gives fans much to anticipate with the funky beat and hilarious plot of the music video.
